The paleomagnetic oven is a sensitive high-precision oven that exhibit non-magnetic heating elements hosted in a magnetically protected mu-metal shield. This enables heating samples in a zero field or in a controlled field conditions. The oven has three independently controlled zones - a large sample zone and two small trimmer end zones - which minimize temperature gradients across the sample zone while keeping overall oven length to a minimum. An additional controlled field coil is wounded inside the inner side of the shields. This coil will produce an axial field of approximately 1 Gauss per ampere of applied current with a maximum field of 10 Gauss.
We upgraded the commercial ASC oven with a laboratory designed Labview operating system and an improved ari flow system for the cooling unit.
